Which of the following is incorrect regarding vasectomy?
Answer: (B) No sperm occurs in epididymis. Answer: (b) No sperm occurs in epididymis Solution: In vasectomy the vas deferens is cut/tied, so sperms produced in the testes still reach and remain present in the epididymis — they simply cannot pass beyond the block into the semen; hence statement (2) is incorrect.
- A.No sperm occurs in seminal fluid
- B.No sperm occurs in epididymis✓
- C.Vasa deferentia is cut and tied
- D.Irreversible sterility
Correct Answer
(B) No sperm occurs in epididymis
Solution & Explanation
Answer: (b) No sperm occurs in epididymis Solution: In vasectomy the vas deferens is cut/tied, so sperms produced in the testes still reach and remain present in the epididymis — they simply cannot pass beyond the block into the semen; hence statement (2) is incorrect. Because the transport is blocked, no sperm occurs in the seminal fluid (1) and the procedure has very poor reversibility, effectively producing terminal sterility (4); the vasa deferentia being cut and tied (3) is the procedure itself.
